Which size boiler would people recommend?

[1-gas]

I have a real dose of bogology on the horizon and have to first fix and install 3 en-suites (with showers), 1 bathroom (with a bath), 14 radiators, 4 towel radiators and a gas cooker along with a combi boiler - which size boiler would you experts recommend? I've never installed such a big system before, my biggest is about 8 radiators with 1 bathroom and 1 en-suite.

Any advice would be greatly appreciated.

Best wishes,

Jay

What would you suggest?

You got g3?

 

[ShaunCorbs]

and have you done a heat loss calc? if not then do one as that can give you your rad sizes and total input needed and add 5kw for a cylinder about

For any advise further to this you need to be a gas safe registered and G3 qualified installer.

If you are, great! Get your post count up to 10 ( talk rubbish, or answer others posts) then message a moderator and your in!
There's loads of great FREE advise.

Thank you, appears the unvented system is the road we will have to go down, I think the customer wanted to avoid having to have a cylinder but not sure that's possible.

Have you had any personal experience of installing a Viessmann 222?

Yes I agree on installing an unvented cylinder with this. I will have to wait until I've updated my Unvented qualie.
